FIG. 1 is a block diagram of a digital photographing apparatus 100, according to an embodiment.

Referring to FIG. 1, the digital photographing apparatus 100 includes an optical unit 101, an imaging device 102, an input signal processor 103, a motor 104, a driving unit 105, a manipulation unit 106, a sensor unit 107, a display unit 120, a processor 130, and a storing unit 140.

A structure of the digital photographing apparatus 100 will now be described in detail.

The optical unit 101 may receive an optical signal from a subject. The optical unit 101 may include a lens that condenses an optical signal, a diaphragm that controls an amount of the optical signal, and a shutter that controls input of the optical signal. The lens may include, for example, a zoom lens that controls a viewing angle to be decreased or increased according to a focal length and a focus lens that focuses on the subject. The zoom lens and the focus lens may each be formed with one lens or a group of a plurality of lenses. The shutter may include a mechanical shutter in which a screen is moved upwards or downwards. Alternatively, instead of an additional shutter, the imaging device 102 may act as the shutter by controlling a supply of an electrical signal.

The motor 104 may drive the optical unit 101. For example, the motor 104 may drive a position of the lens, opening or closing of the diaphragm, and an operation of the shutter to allow the digital photographing apparatus 100 to perform operations such as auto-focusing, automatic exposure control, diaphragm control, zooming, focus changing, and the like.

The driving unit 105 may control the motor 104. For example, the driving unit 105 may control operation of the motor 104 according to a control signal input from the processor 130.

The imaging device 102 may convert an optical signal received by the optical unit 101 into an electrical signal. The imaging device 102 may be a charge coupled device (CCD) sensor array, a complementary metal oxide semiconductor (CMOS) sensor array, or the like.

The input signal processor 103 may digitally convert an electrical signal supplied by the imaging device 102 so as to generate a digital signal. In addition, the input signal processor 103 may perform gain control, noise reduction, signal processing for shaping a waveform, and the like on the electrical signal supplied by the imaging device 102.

The display unit 120 may display an image provided by the input signal processor 103 in real time or may display an image stored in the storing unit 140. The display unit 120 may also display information input by the user or information to be provided to the user, in various forms, such as an icon, a menu, a text, and the like. A liquid crystal display (LCD) device has been illustrated as an example of the display unit 106. However, this should not be construed as limiting. The display unit 106 may include an organic light-emitting diode (OLED), an electrophoresis display apparatus, or the like.

The manipulation unit 106 may include a member that allows the user to manipulate the digital photographing apparatus 100 or to perform various settings during a photographing operation. The manipulation unit 106 may be implemented in the form of a button, a key, a touch panel, a touch screen, a dial, or the like and may receive a user control signal instructing that an operation such as power on/off, photographing start/stop, reproduction start/stop/search, driving of an optical system, mode conversion, menu manipulation, selection manipulation, or the like is to be performed.

The sensor unit 107 may convert information about an inside or an outside of the digital photographing apparatus 100 into an electrical signal. The digital photographing apparatus 100 may not include the sensor unit 107.

The sensor unit 107 may include at least one of a position sensor, an azimuth sensor, a gradient sensor, and a height sensor. As an example, the position sensor may receive at least one satellite signal and may process the received signal, thereby determining a position of the digital photographing apparatus 100 on the earth. The position sensor may provide a latitude value, a longitude value, or the like of the digital photographing apparatus 100 based on the determined position. The azimuth sensor may measure an azimuth value of the digital photographing apparatus 100. For example, the azimuth sensor may measure an intensity or a flow of a magnetic field generated by the earth and may process the measured signal, thereby providing the azimuth value of the digital photographing apparatus 100. The gradient sensor may measure speed and gradient direction change of the digital photographing apparatus 100. For example, the gradient sensor may measure vector values on three axes such as an x-axis, a y-axis, and a z-axis and may provide displacement values corresponding to the three axes each hour. The height sensor may measure a height value of the digital photographing apparatus 100. For example, the height sensor may include one or more acceleration sensors and a magnetic sensor. The height sensor may provide the height value of the digital photographing apparatus 100 by using values of the three axes measured by the acceleration sensors and the magnetic sensor.

The storing unit 140 may include data required for operation of the digital photographing apparatus 100 and data in various forms for the user. For example, the storing unit 140 may include data input by the input signal processor 103, data used for an arithmetic operation, an algorithm required for operation of a digital camera, setting data, and the like and may store a processing result temporarily. In addition, the storing unit 140 may store an image file generated by compressing the data input by the input signal processor 103 and may also store files in various forms. An embedded memory embedded in the digital photographing apparatus 100 or an external memory may be used as the storing unit 140. The storing unit 140 may be Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), Read Only Memory (ROM), flash memory, a hard disk, a Secure Digital (SD) memory card, a Multi-Media Card (MMC), an optical disc, an optical magnetic disc, hologram memory, or the like.

The processor 130 may process an image by performing a digital operation. For example, the processor 130 may reduce noise that occurs in an image and may perform image signal processing such as gamma correction, color filter interpolation, color matrix, color correction, color enhancement, and the like, for improvement in image quality. In addition, the processor 130 may generate an image file by compressing an image generated by performing image signal processing and may restore the image from the generated image file. An image may be reversibly compressed or irreversibly compressed. An example of a proper format that an image may be compressed into may be a Joint Photographic Experts Group (JPEG) format or a JPEG 2000 format. The processor 130 may further perform functions such as sharpness processing, color processing, blur processing, edge emphasis processing, image interpretation processing, image recognition processing, image effect processing, and the like. The processor 130 may further perform image signal processing for displaying an image on the display unit 120. For example, the processor 130 may perform brightness level adjustment, color correction, contrast adjustment, contour emphasis adjustment, screen division processing, generation of a character image, image synthesis processing, and the like.

The processor 130 may perform the above-described image signal processing and may control each element according to a result of the processing. The processor 130 may further control each element according to a user control signal input by the manipulation unit 106.

Furthermore, the processor 120 may obtain a second image that was captured within a predetermined distance in a first direction from where a first image from among a plurality of images stored in the storing unit 140 was captured, from the plurality of images, and may provide the obtained second image to the display unit 120, in response to a user's input for selection of a user interface corresponding to the first direction.

In addition, the display controller 131 may provide a user interface for displaying a second image stored in the storing unit 140 or the external device of the digital photographing apparatus 100 on the display unit 120. As an example, the display controller 131 may provide a user interface for displaying a second image that was captured within a predetermined distance in a first direction from where the first image was captured, on the display unit 120. As another example, the display controller 131 may provide a user interface for displaying a second image that was captured in a first direction within a predetermined angle from a height at which the first image was captured, on the display unit 120. As another example, the display controller 131 may provide a user interface for displaying a second image that was captured in a first direction within a predetermined angle from an azimuth angle at which the first image was captured, on the display unit 120. As another example, the display controller 131 may provide a user interface for displaying a second image that was captured at a zoom magnification different from a zoom magnification at which the first image was captured, from where the first image was captured, on the display unit 120. Here, the zoom magnification may be a zoom magnification at which a size of a subject in the first image is decreased or increased. The zoom magnification may be changed by controlling the focal length, for example.

When the first image is displayed on the display unit 120, the obtaining unit 132 may obtain a second image that was captured within a predetermined distance in a first direction from where the first image was captured, from the plurality of images stored in the storing unit 140 or the external device of the digital photographing apparatus 100.

In this regard, the first direction may be a direction from where the first image was captured to where the second image was captured. For example, the first direction may be one from among upward, downward, left, right, and diagonal directions.

According to another embodiment, the obtaining unit 132 may obtain a second image that was captured in a first direction within a predetermined angle from the height at which the first image was captured, from among the plurality of images stored in the storing unit 140 or the external device of the digital photographing apparatus 100. In this regard, the obtaining unit 132 may obtain the second image by using height information about each image. Here, the first direction may be a direction in which the second image was captured at the height at which the first image was captured. For example, the first direction may be an upward direction or a downward direction.

In this regard, the obtaining unit 132 may obtain the second image by using azimuth information about each of the first image and the second image. In this regard, the first direction may be a direction in which the second image was captured from where the first image was captured. For example, the first direction may be a left or right direction.

According to another embodiment, the obtaining unit 132 may obtain a second image that was captured at a predetermined zoom magnification from where the first image was captured, from among the plurality of images stored in the storing unit 140 or the external device of the digital photographing apparatus 100. In this regard, the second image may be obtained by using zoom magnification information about each of the first image and the second image. In this regard, the predetermined zoom magnification may be a high or low zoom magnification based on the zoom magnification at which the first image was captured.

Additional information such as position information, height information, azimuth information, zoom magnification, and the like about an image may be stored in the storing unit 140 together with the image or as a separate file.
